Decline in Brain Function, Cognitive Degeneration or Dementia in Dogs

As veterinary medicine advances and pet care improves, their lifespan is extending, which means many age-related conditions that appear in old age are becoming more common. This is also the case with dementia, a condition we describe in humans – but with the same symptoms appearing in dogs, which we call cognitive dysfunction syndrome.

In one study, about 50% of dogs older than 11 years showed at least one sign of CCD. Another study showed that 68% of dogs between 15 and 16 years may show at least one sign of CCD.

Cognitive dysfunction is directly linked to brain aging. Deficits in learning and memory abilities, as well as reduced response to stimuli, are symptoms of the disease. The causes are unknown and it is speculated to be a combination of factors that occur with aging. The number of nerve cells decreases as dogs age, and symptoms always progress.

Diagnosis

A veterinarian can diagnose cognitive decline if examination and laboratory tests show that the animal’s behavior has no other cause, such as hypothyroidism, Cushing’s disease, hyperthyroidism, loss of vision or hearing. Some behavioral problems can also mimic this disease, such as separation anxiety.

Here are several signs that may indicate canine dementia

Disorientation

Staring into space or getting lost in familiar surroundings. Your dog may not be able to find their way in and out of the house, or may get stuck in corners or under tables, act confused, bark for no reason and pace around.

Changes in Sleep-Wake Cycle

The dog becomes restless in the evening or throughout the night. Some dogs with dementia won’t sleep at all, while others will wake frequently, be restless, etc. Barks at night for no clear reason, sleeps all day.

Changes in Interaction

Their character seems to change and they may show decreased affection or become overly attached. Some will become irritable and grumpy.

No Longer House-Trained

Forgets to “ask” to go to the bathroom. Interaction with them becomes more difficult.
